Consider replacing the current "cardiovascular system phenotype" header term with "circulatory system phenotype". We need additional terms to properly describe the lymphatic system vessels and circulation; these are currently in a mismash of inappropriate places. If we make cardiovascular more general into circulatory, these terms could be accommodated under this new header.
See new term abnormal lymphatic system physiology MP:0010368; currently placed under cardiovascular system phys (not correct.)
For MGI only, this may involve some data migration of annotations to high level terms? Consider the ramifications; header term files will also need to be modified and the WI allele detail page display may need to be modified. Check on this. The modifications may need to be postponed for a WI software release.
